T0 all 107mm it 71mg con/ocra.-

Be it known that l, JOHN SHANKs, a subject .3 of the Queen ofi' Great Britain and Ireland, and a resident oit larrhead, Vin the county ot' Renfrew, Scotland, have invented certain linprovements in later-Closet Basins, (for which l have obtained-British latent, dated Decembcrl), 1885, No. l5,;oo,) oi' which the `following is a speciiication. p My said invention has for its object to improve the construction and action ot' waterclosets made with basins of the wash-out kind. l In carrying out my invention the basin is l made with two distinct water-inlets Oneinlet is at the top of the basin and communicates with a hollow rim to distribute the water, and the other inlet is in a lower position ,L facing the main discharge-outlet from the basin. In addition, there is a third water-.inlet of small size from a pocket or small compartment made with an opening at the top to rei ceive water :t'roin the main liushingstream andto deliver itinto thebasin slowly, so as to act as an after-service for filling the bottom ol the basin. .lhebasin is by preference to be placed with its main discharge-outlet at the t'ront side, this outlet leading down to a trap-bend 'formed immediately beneath the basin. An explanatory drawing is hereunto appended, showing in vertical section a watercloset basin as made with my improvements. My improved water-closet basin (5 is olf what is known as the wash-out7 kind, and is made with two distinct inlets, 7 8, tor the main supply of liushingavater, which is supplied by a pipe (not shown) connected to the horn l2. One, '7, of the water-inlets is in the common position at the top of the basin t3, and is in communication with a hollow rim, O, ar ranged to distribute the water round the basin, and made with one or more slits at itsbottom tor that ptn-pose. ,lhe other water-inlet, S, is in a lower position at the level of the water which is retained in the bottom of the basin, and it faces the main discharge-outlet 10, so that the force ol' the jet enteringl by it is well directed lor sweeping the contents ol' the basin G into the discharge-outlet; and to give the fullest action to the jet the pipe or passage ll, leading to this lower inlet, 8, is, with the horn 12, made a direct continuation of the main water-supply pipe, the upper inlet, 7, being supplied by a branch, 13, therefrom. The inlets 7 S, with the passages 13 ll leading to them, are made in the saine piece with the basin o, so that there is only a single joint connecting themv to the main water-supply pipe. This improved arrangement of the basin-inlets 7 8 has combined with it a simple device :for supplying a little water as an after-service to insure the filling ot the bottom of the basin. This device conl sists otv a pocket or small compartment, ll,

having an opening atthe top to receive water from the upper inlet branch passage, 13, while there is at the bottom of the pocket a small orifice, l5, leading into the basin. The pocket ll becomes more or less iilled while the main flushing-stream is being delivered;

but it empties itself slowly because of the sinallness of the bottom orice, l5, so that enough remains for the intended purpose after the main supply has ended. A trap-bend passage, 16, is formed beneath the basin (i, no part of the discharge-outlet l0 or of the 1 basin proper forming any part of the trap.

The drain-pipo (not shown) may be connected at l? at the backi of the basin-piece; or the basin-pieec may be modified in torni, as indicated by dotted lines, so that the drain-pipe may be connected at 1S at the bottom.

what lclaim as my invention is- A rater-closet basin having combined in it a main dischargeoutlet at the side leading down .i nto a trap-bend passage below the basin, a concave basin-bottom dipping a little lower than the bottom edge of the main outlet, an upper water-'flushing inlet, a hollow slit distributi iig-rim, a lower water-tl ushi n g inlet facing the main d ischarge-ontlet and at the level of the water retained in the basin-bottom, a passage leading to the lower flushing-inlet directly from the horn to which the water-supply pipe is connected, and an after-service pocket with a top opening to receive water from the [iushing-streain and with a small bottoni oritice or inlet into thebasin, the said several parts being all made in one piece, and substantially as herein set forth.

In testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses.

JOHN SHANKS.
